How hemoglobin binds to gases in the blood
Web18 jul. 2016 · The Binding of Oxygen and Hemoglobin Is Determined by Oxygen Tension. Figure 48-3 shows that the oxygen content of blood—that is, the amount of oxygen combined with hemoglobin—is determined by P O 2.At a P O 2 of more than approximately 70 mm Hg, the oxyhemoglobin dissociation curve is virtually flat, which indicates that … WebCarbon monoxide (CO) is a colorless, odorless gas found in furnace and automobile engine exhaust and cigarette smoke. CO binds to hemoglobin 210 times more tightly than does O2. CO also binds with an electron transport protein and disrupts cellular respiration. Explain why CO is such a deadly gas.
